Miley Cyrus — who has been spotted smooching Aussie actor (and Last Song costar) Liam Hemsworth — doesn't have any plans for Valentine's Day this year.

"Work," she told UsMagazine.com when asked how she'll spend the day. "I'm really boring."

During an E! pre-Grammy show, she denied rumors that she's engaged – or that she's been wearing a promise ring. "I bought it myself," Cyrus, 17, said of the bling. "And I got it made in London, and everyone thought it was diamond when it wasn't. It was the cheapest thing ever … So if I do get a promise ring, it better be real!"

Cyrus — who told Us she looked forward to seeing Lady Gaga the most at the Grammys — said she tried on three dresses for Sunday's show.

"I hate trying on clothes – I cannot do it!" she said on the red carpet. "They pin you forever."

She eventually settled on a Herve Leger by Max Azria frock.

"I like it because it wasn't stuffy," Cyrus told Us. "I wanted to be edgy."
